 Note: Harpella melusinae has larger thalli and trichospores than H. meridianalis, and a very distinctive, tapered holdfast (Reichle and Lichtwardt, 1972). H. meridianalis more closely resembles H. leptosa (Moss and Lichtwardt, 1980), but its trichospores are shorter and generally narrower, and the more rounded thallial base has a broader secreted holdfast than H. leptosa.
